like d said, if you are ever in doubt of stray pollen in your room, simply mist entire room/plants down as soon as you notice. water kills pollen...
if you have clones of your plants rooted, why not just clean entire room out, give it a nice cleaning, and start those clones. of course if you have no clones of your girls, i'm pretty sure you can reveg the girls once the stray herm pollen is dealt with. you'll need to flip your lights back to 24/7 and begin veg again...
a sulphur burn is not what is needed.
do you know for certain which plant hermied on you? if you do not, you should toss all plants and clones, clean room, and start over from step one.

(i know, really sucks)...
sorry, just reread about clones in separate veg room. ok, grab a mister bottle and mist down all veg plants, and scrub the veg room, and if you know what plant hermed, toss those clones. if you use a number/marker system for id purpose, and you know the herm plant, it will be an easy transition.
don't wait on misting though. do it immediately...
either get some timers that are user friendly, or learn from your mistake, and figure out the ones you have...
burning an entire crop hurts, but don't dote on it to much now. instead make a plan and jump right back on another crop immediately. accidents happen to everyone at some point, learn from them, and trudge onward...peace...
